To all whom it may concern.-

Be it known that I, BERNHARD WERTHEl- MEB, a subject of the Emperor ofGermany, residing in Carlsruhe, Germany, have invented new and usefulImprovements in CigarlEnnching Machines, of which the following is aspecification.

My invention relates to improvements inthat class of machines which areused in the manufacture of cigars, the machine being specially adaptedto roll the wrappers upon the fillers and to automatically deliver thecompleted cigar into a form.

The object of the invention is to produce a machine which, while notentirely making a cigar, will greatly facilitate the manufacture andwill form the cigar in such shape that the tobacco composing it will beevenly distributed and will roll the bunch symmetrically, an essentialfeature of the machine being the means by which the filler is placed ina loop of the wrapping-cloth without injury.

My invention relates to improvements in cigar-bunching machines; and theobject of my invention is to produce a machine which will rapidly roll asymmetrical bunch and deliver it into a matrix of a mold.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of one form of rolling-table and shows thearrangement of the aprons which envelop the filler while it is bcin grolled. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 isaloroken detail view of the gear mechanism for turning the filler-mold.Fig. 4 is a detail sectional view of a modified form of therolling-table, having the filler-moldformed integral with it, the viewshowing also the progressive positions of the filler, aprons, andbunchingroller during the rolling process. Fig. 5 is a similar view of amodification of the rolling mechanism shown in Fig. 4, showing a slottedtable, a slide to cover the slot, and a supplemental roller. Fig. 6 is aview similar to Fig. 5, but with the bunching and supplemental rollersin a more advanced position. Fig. 7 is a vertical sectional view of apreferred form of table and filler-mold, the side pieces being removedfrom the table. Fig. 7 is a detail plan view of the double mold. Fig. 8is a broken detail plan of the tension-roller and aprons and the meansof adjusting the aprons. Fig. 9 is a broken detail sectional view of amodified form of rolling-table with a form connected therewith and meansfor actuating the form. Fig. 10 is a broken sectional plan of theform-operating mechanism.

Fig. 11 is a sectional elevation of the con-' nected rolling-table andform, as in Fig. 9, but with the latch in position to pressabunch into amatrix of the form, the view showing also a filler-mold in section; andFig. 12 is a broken sectional plan of the connected form and table.

In carrying out the invention'the filler is formed in the usual way,either by rolling it upon the rolling-table or upon the knee. Therolling table or frame A of the machine has a flat top, across whichextends longitudinally the aprons or bands B, the bands being arrangedparallel with each other and slightly overlapping, as shown in Fig. 8,and having their ends severally secured at one end of the machine to therollers D D D and the opposite ends of the aprons are secured betweenthe clamp E on the opposite end of the machine, as shown in Fig. 7, theclamp comprising two similar plates, which are closed upon the aprons,and which are connected with the springs 6 upon the lower edges, thevertical movement of the clamp being limited by the stops E above andbelow it. The clamp thus gives the necessary elasticity to the aprons;but instead of using the clamp E the aprons may be attached directly toa spring E on the under side of the tabletop, the apron being doubledover one end of the table, as shown in Fig. 9, for the purpose.

The aprons are given the proper tension by the tension-roller D, whichextends transversely across the machine-frame in front of theapronrollers D D D and which rests uponthe upper surface of the aprons,the ends (Z of the roller being reduced and made to extend throughvertical transverse slots a in the side of the machine-frame, so as topermit of the necessary vertical movement of the roller. The object ofhaving the several aprons and an adj Listing-roller for each apron is toprevent the cylindrical form of .the bunch, as the outside aprons may bedrawn tighter than the central apron, thus causing the bunch to betapered at the ends. I'Vhen the outside aprons are tightened, asdescribed, they draw harder on the ends of the bunch than the centerapron does on the middle of it, and as a result the tip and reduced endare formed. A roller D is also arranged a little-above the roller Dandbetween it and the band-rollers above mentioned, and the aprons are madeto extend below the tensionroller D and above the roller D.

A filler-mold O is mounted in a recess in the upper side of the table orframe A, the said mold being concave on its upper and lower sides toreceive a filler, and the mold has atone end a gear-wheel C, whichconnects with suitable mechanism, as described below, to rotate the moldand turn it over, the ends of the mold beingpivoted in suitable supportsto enable it to turn easily. The gear-wheel 0' turns loosely on one ofthe trunnions of the mold C, and fixed to the moldis a ratchetwheel 0which is engaged by a pawl c, carried by the gear-wheel, so that thegear-wheel may turn freely in one direction without actuating the mold,and when turned in the op posite direction the pawl by engaging theratchet-wheel will cause the mold to turn.

The ends of the aprons are fixed to the rollers D D and D, as alreadydescribed, and the ends of the rollers are provided with worm-wheels cl,which mesh with worms F, arranged at right angles to the rollers, sothat by turning the worms the gears and rollers may be also turned, thusrolling the aprons upon the rollers and giving to them the necessarytension.

On each side of the machine-frame A are side pieces G, which projectabove the surface of the table-top, and which are secured to the tableor frame by means of the bolts g, which extend through vertical slots atin the sides of the frame, thus affording means for vertically adjusting the said pieces. The side pieces G have a slotted track Gtherein, which extends for the most part parallel with the tabletop A,and a little above the same, but which is curved upwardly at its rearend, and at its forward end is curved downward so as to be opposite theends of the transverse recess A in the table-top, said recess beingdirectly in the rear of the mold O.

A shaft I extends transversely through the lower portion of themachine-frame, and eX- tending radially from one side of the shaft is asegmental arm I, the outer end of which is provided with teeth whichmesh with the gear-wheel C on the end of the mold C, so that when theshaft I is oscillated the move ment will be transmitted to the mold, theparts being arranged so that the mold will be turned through an arc ofone hundred and eighty degrees. The shaft I has also a weight I attachedthereto by means of a suitable arm, and the weight is arranged inrelation to the arm I so that when it drops into its normal position, asshown in Fig. 2, the upper teeth of the arm I will be in engagement withthe gear-wheel C, thus holding the mold C in position to receive thefiller. A pulley I is fixed to the shaft I and a chain or strap l; isattached to the pulley, the free end of the said strap connecting with asuitable treadle, so that by pressing the treadle the shaft will beturned in one direction, and upon removing the pressure the weight Iturns the shaft in the opposite direction.

On opposite ends of the shaft I are the arms I the arms being arrangedon the outer sides of the machine-frame, and the ends of the arms extendopposite the slotted track G in the side pieces G, and are slotted, asshown at t", to receive the ends of a shaft II, which carries abunching-roller II, the roller being arranged beneath the aprons B andbeing provided with ball-bearings having balls 71., which turn insuitable grooves in the shaft II tion-rollers, as h, at each end toenable it to run easily in the tracks G The arms I are placed upon theshaft I in such a manner that when the machine is at rest, as shown inFig. 2, the arms will be opposite the recess A in the front end of thetable or frame, and the roller H will extend through the recess.

hen a bunch is to be rolled, the filler is placed in the mold 0 abovethe aprons B, and the cigar-wrappers are placed upon the aprons behindthe filler. The operator then stops upon the treadle, thus turning thepulley I and the shaft I, raising the arm I and Weight I and moving thearms I, and when the arms are moved they cause the shaft II to travelalong the grooved tra k G, thus raising the bunching-roller II andcarrying the aprons B over the filler; and that this operation may benicely performed the side pieces G are adjusted so as to bring thebunchingroller a proper distance above the filler. This movement of thebunching-roller I l carries the apron around the filler, as described,and when the bunching-roller reaches this point the aprons have beendrawn to their limit, and the continued movement of the bunching-rollerraises the filler from the mold and rolls it in a well-known manner uponthe table, thus enveloping it by the wrappers or The shaft II shouldhave suitable fric-,

IlO

binders when they are spread in front of the mold, as described below.The movement of the launching-roller is clearly shown in Figs. 4 and 5,and in Fig. at the mold is shown as made integrally with therolling-table. \Vhen the pressure upon the treadle is removed, theWeight 1 drops beneath the shaft, thus turning the shaft and carryingthe arms I and I back to their normal position, and during this movementthe segmental arm I, operating on the gear-wheel C and ratchet-wheel Ctips the mold 0 completely over; and it will be observed in thisconnection that the mold, which is shaped to receive the filler, has oneside with its point to the right and the opposite side with its point tothe left,and as the mold is automatically tipped back and forth,

as described, it is thus adapted to be used in connection with eitherright hand or left hand over leaves and wrappers. The double form ofmold described above is the preferred form and is shown in Figs. 7 and 7To provide against too much one-side pressure from the wrapping-rollerH, the following mechanism is used: A shaft'K extends transverselythrough the machine-frame in front of and a little above the shaft I,and fixed to the shaft near each end is a hub L, having the curved armsL and L radiating therefrom.

The arms L are curved and made to extend to a pointjust in front of themold G, the arms being slotted to receive a supplemental roller Z, whichextends transversely across the machine-frame, and the slotted arms areprovided with afollower Z to hold the roller in place. The lower arms Lare curved atthe ends and extend opposite and a little above the shaftI, the shaft having cams M to actuate the arms, and the arms havingsuitable trucks Z in the ends to reduce friction between the arms andcams. The cam M is shaped to rock the arms L and L so that during the upWard movement of the roller H and filler, as described above, the rollerZ will force the aprons B against the lower side of the filler and presslightly against the filler until it reaches the table-top, and when thebunchingroller is used, as described, the table-top is provided with aprolongation or flange a which extends well into the recess occupied bythe mold O. The supplemental roller and its actuating mechanismdescribed above are used in the form of machine shown in Fig. 7.

In Fig. 8 I have shown means for preventing the displacement of theaprons B and holding them in position upon the tensionroller D, whichconsists of two arms d attached loosely to opposite ends of the rollerand carrying a cross-bar (F, on which are adjustably mounted the blocks(1 the inner ends of the blocks being rounded to press lightly upon theaprons, and being also provided with suitable shoulders, so that theymay be pressed simultaneously upon two aprons, the blocks beingadjustable by means of suitable thumb-screws (2 In Figs. 9 to 12,inclusive, I have shown means for delivering the completed bunches upona form. The form-plate Nhas the usual forms or molds N extendingtransversely across it, each being adapted to receive and shape a bunch,and the plate is mounted obliquely at the right hand of the table-topupon suitable rollers N, which turn upon the shafts N The form-plate Nis actuated by a toothed Wheel 0, which meshes with the lower portion ofthe form on the plate, the

wheel being secured upon a shaft 0, which turns in suitable bearings,and which has also a ratchet-wheel O affixed thereto, and means areprovided, as described below, for raising the form-plate a distance ofone form or bunch each time a cigar is rolled, and in order that theplate may move accurately the end of the table top or frame A is shapedso as to form a guideway between it and the rollers N A split lever P ispivoted atone end on the shaft 0, its opposite end being slotted, asshown, and connected with a crank Q on the main shaft I of the machine,the lever carrying a spring-pressed pawl 19, which engages theratchet-wheel O and turns the Wheel and the shaft to which it is affixedwhen the shaft I is turned in one direction, and to prevent theratchet-wheel and shaft from turning back a pawl p is provided, the pawlbeing pivoted upon a suitable support opposite the pawl 19. A latch Rextends transversely across the table-top near its rear end and oppositethe form-plate N, the latch being fixed upon a suitable shaft R, whichis connected ateach end by means of cranks r and levers S with the shortarms S, which are fixed to the main shaft I, the arms S being made toextend oppositely to the armsl which receive the shaft H of thebunching-roller H, as already described.

As shown in Figs. 9 and 11, the aprons B are doubled beneath thetable-top, being held in place by the roller u and guided around the endof the table through a slot in the same by means of a roller it. It willbe noticed in this connection that the rear end of the table-top isinclined downwardly, so that the bunches which are rolled thereon willeasily enter the forms N of the form-plate N at the end of the table.

lVhen the shaft I is actuated to roll the bunch in the manner alreadydescribed, the levers S, cranks r, and shaft R are also actuated, andduring the forward movement of the bunching-roller H the latch R israised to the position shown in Fig. 9. Upon the return movement of the-bunching-roller and its actuating arms or levers the formed bunch rollsdown the incline at the rear end of the table into one of the forms N ofthe formplate, and the latch R is forced downward upon the bunch, thuspressing it firmly into the form, when the shaftI is again actuated torepeat the operation. The crank Q, lever P, and pawl 19 actuate theratchet-wheel O shaft 0', and toothed wheel 0, thus raising theform-plate the distance of one form, so that it is ready to receiveanother bunch.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A cigar-bunching machinehaving a plurality ofparallel bunchingv-aprons arranged side by side, said aprons beingindependently adjustable in length in relation to each other,substantially as described.
